DONGYANG, China, Dec. 7, 2023/PRNewswire/ -- Recently, DMEGC Solar's PV modules successfully obtained the IEC TS 63209-1:2021 extended stress test certification issued by TÜV Rheinland, proving once again the excellent quality and reliable performance of its module products.
IEC 63209 is an international standard for expansion voltage testing of photovoltaic modules, published by the International Electrotechnical Commission (IEC). The updated IEC 63209-1:2021 standard specifies test methods and requirements for ground-mounted photovoltaic modules, including maximum power point tracking tests, performance tests, environmental adaptability tests, safety performance tests and tests. of durability. These tests can help manufacturers better evaluate the performance and quality of PV modules and improve product design accordingly to improve reliability and durability.
The series of tests performed on DMEGC N-type solar modules covered multiple tests according to IEC 63209-1:2021, including thermal cycle test TC200 (-40°C to 85°C, 200 cycles)/TC400 (2 times intensified) /TC600(3 times intensified), DH1000 damp heat test (temperature 85°C, relative humidity 85%, 1,000 hours)/DH2000(2 times intensified), mechanical load test (static load SML dynamic load DML cycles thermal tests TC50 humidity freeze cycle HF10), ultraviolet composite test (DH200 (UV60 TC50 HF10)x3 UV6.5) and PID test PID192 (2 times intensified).
Test results showed that DMEGC N-type solar modules performed exceptionally well in all reliability tests, with a decay rate well below the IEC standard of 5%. The drop rates in all basic and intensified test sequences, such as TC, PID, DH, UV and DML, were within 2%, with PID performance even lower than 0.6%. The overall performance not only exceeded that of P-type modules of the same size, but also surpassed most N-type modules of other brands. Furthermore, there were no significant changes before and after EL detection, demonstrating ultra-high reliability. It should be noted that the components used in this test were randomly selected from mass production, with model DMXXXM10T-B78, which means that the mechanical loading performance of the large-size 78-cell double-bifacial glass modules met the intensified testing standards. This outstanding reliability performance demonstrates that DMEGC Solar is at the forefront of the industry in terms of module reliability.
With the continuous launch of DMEGC N-type series solar modules, their excellent reliability serves as a guarantee for solutions in all scenarios, such as residential, commercial and industrial and utility applications, bringing greater value to users of different types and leading the path to unlimited possibilities in photovoltaic development.
